An electrode is an electronic electrical conductor in contact with an electrolyte. In a cell carrying sustained redox electric current, chemical reactions at this interface exchange electrons with chemical species. An electrode can participate in the chemical reaction, as the dissolving zinc anode of a Daniell cell does, or provide a conducting surface without appearing in the net chemical equation. This distinction is illustrated by active and inert electrodes in Flowers, Theopold, Langley and Robinson, Chemistry 2e, §17.2.
